Symptoms of Melanoma

Melanomas are not usually painful. The first sign of melanoma is often a change in the size, shape, color, or feel of an existing mole. Melanomas can also appear as a new, black, or abnormal mole. It is important to remember that most people have moles and almost all moles are benign. Report any changes to your doctor.

Changes in Existing Moles

Spotting a mole that seems out of the ordinary may be the first warning sign of melanoma. The ABCDE rule highlights suspicious mole characteristics:

A—Asymmetry

When you look at a normal mole, it is even in shape all the way around. An asymmetrical mole has 2 halves that do not look the same. For example, one side is round and the other is not.

In most cases, moles are brown and evenly colored throughout. However, some moles are tan and black. Changes in the color of the mole may be indicated by different shades of brown, tan, or black. Sometimes, you may notice white, gray, pink, or red mixed. The important point is the change and unevenness of the coloring.
